NBC Learn and NBC Sports, in partnership with the National Science Foundation and the National Hockey League, explore the science and math behind professional hockey.

Make science and math more interesting to students by including this informative 10-week video series into your curriculum. Explore the geometry found on the hockey playing surface, examine the physics of a slap shot using the principals of work, energy and power, see how vectors impact the passing game, learn why statistics and averages are important to professional players, and much, much more.

### Hockey Geometry

Where in a NHL game or on a NHL rink do you see geometry? This segment explores the importance of geometry in the game, from divisions of the zones of play on the ice surface to the various angles of the hockey stick, puck movement, and the angle of access that goaltenders use to protect their net.

### Work, Energy & Power

In this segment, Dallas Stars Left Wing Brenden Morrow talks about the force behind their powerful slap shots. A slap shot is the perfect demonstration of work, energy and power, and this segment breaks down these concepts to show how they combine into one speedy projectile of a puck.

### Vectors

Passing is one of the most important skills in hockey, and geometry is a huge part of it. This segment discusses how velocity vectors play a key role in getting a puck from point A to point B with speed and accuracy, a crucial part to any hockey game.

### Statistics & Averages

Goaltending is not just a game of reflexes, but also involves having head for numbers, namely statistics and percentages. This segment explains how a goalie must take into account the statistics of the other teams' players, as well as keep in mind their own save percentage, which is a direct indicator of their success in the game.

### Reflexes & Reaction Time

Hockey goaltenders' entire careers hinge on their lightning-fast reflexes and reaction time. This segment explores the importance of the goalies' reaction to the stimulus of the puck coming toward them and how their reflexes play a key role in everything they do.

### Projectile Motion

This segment discusses the accuracy involved in a wrist shot, and how it relates to the concept of projectile motion. A wrist shot is able to be directed to an exact spot through a combination of pointing the stick in the correct way and putting the correct spin on the puck, all of which relate back to the properties of projectile motion.

### Newton's Three Laws of Motion

Newton's Laws of Motion apply to every moving object, and hockey is no exception. In this segment, Newton's Three Laws of Motion, as well as concepts of inertia and forces, are applied in every aspect of the game, from players themselves, skating and checking, to the puck, and every shot and pass in between.

### Mass, Volume & Density

Though it's an under-publicized job, the ice technician is one of the most important people when it comes to producing a hockey game. This segment discusses what an ice technician does, how the ice for the game is created, and how the mass, volume, and density of the water play a major role in the planning and execution of putting the rink together.

### Kinematics

The principals of kinematics, velocity, position, and acceleration, are key components in hockey players' abilities to skate across the ice. This segment explains how these concepts come together to allow a player to predict another players' location at a future point in time, and other important information about the player.

### Force, Impulse and Collisions

This segment illustrates a perfect example of collisions and opposing forces, the puck in a hockey game. The force exerted on the puck by a stick, the boards, or a player, determines exactly how fast it will move and in what direction, as well as how impulses play into it all.
